Construction crews have started to redo a building at 1492 Park Ave. that once was the location of a day spa.

The building will be redeveloped into offices, the general contractor working at the site says. Jamie Catley, the owner of Kent Construction, says a second level will be added.

Catley anticipates the project will be completed early in the summer.

The work is proceeding after what Catley describes as different interpretations of the City Hall permit allowing a partial demolition at the site.

Chad Root, Park City's chief building official, says permits issued by City Hall allowed the crews to remove roof materials like shingles and stucco on the walls as well as the demolition of the inside space.

Root says the crews, though, began removing the entire roof without City Hall authorization. The Building Department was worried that the Park Avenue-facing wall could collapse outward if a windstorm occurred and was concerned the rest of the roof could cave in.

The Building Department allowed the workers to continue removing the roof for safety reasons, Root says.

The south-facing wall will remain standing and be incorporated into the redone project while the rest of the building will be taken down, according to Root.

It is not a historic building that would have been afforded further protections from a demolition.
